T0 all whom. it may concern:

Be itknown th at I, ALBERT FORBES CoNANT,

of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Pocket Memorandum- Books, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

In said drawings,Figure l is a plan view of a memorandum-book embodying my invention. Fig. 2 is also a plan view, but showing the book as with the top lid or cover opened. Fig. 3 is a plan view of the leaves of paper as detached from the cover and in the same relative position as in Fig. l. Fig. 4 is a vertical section taken on Y Y, Fig. l, and doubled in size as compared with Fig. l. Fig. 5 is an enlarged detached section taken as on line Z, Fig. l, through one of the lids of the cover and viewed as from the right in said figure. Fig. 6 is aplan view of my memorandum-book in its transfer-cover. Fig. 7 is an edge view of the book as shown in Fig. G.

This invention relates to what are known as pocket memorandum-books;77 and it-consists in features of novelty7 hereinafter described, and pointed out in the claims.

Referring again to the drawings, a a represent two thin metal plates, which at theirv lineally central portion are slightly raised, as at b, and a slot c is formed near the edge of said plates, and extending from part t) to near the ends, thus forming the narrow bar d. (See Figs. l and 5.) To these plates a a', respectively, are secured the lids e of the cover, preferably formed of smooth, stiff, finely-finished cardboard, the lids being hinged to said plates by means of. strips of cloth f, inserted in slots c, folded on bars d, and pasted upon the opposite sides of the lids.

For the purpose of clamping the leaves p, of paper, between covers e, l have invented the telescopic screw-clamp A, (shown in enlarged detail in Fig. 4,) the solid section g of which is secured to plate a by its stud w, and the hollow section h is secured to plate a by the stairfstepped stud j 7c, formed upon the back of disk t, which is inserted and secured in the-section h, 'as shown in Fig. 4, said stud la being secured to a washer Z, inserted in a seat in plate a', as shown. One or more secn tions m, having each an external and internal circumferential flange, may be interposed between sections g h, as shown, the section g and each intermediate section being externally threaded to engage with the thread of the internal ange of the next larger section, as shown. As washer Z turns freely in its seat in plate a', thus allowing section h to be rotated, while section g is rigidly secured to plate a, .therefore by .rotating section h the entire series may be extended, as shown in Fig. at, or may be telescoped together till plate a rests upon section h. The sections m are provided with an interior flange n at their larger end to liinit the telescopic Inovement of the coacting smaller section, if for any cause it should commence such Inovement before the sections smaller than itself were fully retracted, as in such case the screwthreads of coacting parts would be disconnected.

The sheets of Ypaper p have a'seat q cut therein of a size to receive section'h of clamp A, so that when the desired number of leaves are placed between plates a a they may, by properly rotating section h, be firmly secured in place between said plates, thus, with lids e serving as covers, constituting a memorandum-book.

For the .purpose of preserving the contents or subject-matter recorded upon leaves p after-they have been written upon l form in the edges of the leaves, opposite seat q, the small seats s, and I provide the lids e e', of pasteboard or other suitable material, having corresponding notches s in their edges, as shown in Figs. 6 and 7, said lids being cut and provided with the cloth hinge as shown in said iigures.

By unscrewing clamp A and taking the leaves bodily from between lids e, and then placing them between lids e and clamping the whole together by elastic band t, the entire contents remain in order and available for futurereference whenever desired.

For the purpose of providing a convenient and permanent index to the contents of the memorandum-book l form the leaves p of different-colored paper-for instance, a p0rtion of the leaves being blue, others yellow, others pink, others drab, heg-all the leaves of each color beingl arranged together and IOO there being as many colors and shades as may be desired. I also paste upon the inside of one or both lids, as may be necessary, at the left-hand margin, small squares of paper of the several colors from which the leaves are selected, such color samples being represented at u u, Fig. 2, and upon the line or lines c, opposite such samples, I insert the requisite instructions or data-such, for instance, as Engagements, Stock quotations, To attend to at office, Bank account, ne.

In practice, if it is desired to refer to any memorandum entered in the body of the book, it is only necessary to turn to the proper heading on the lid or lines'fu and, observing the color or shade opposite thereto at u, then turn to the leaves of the same color1 or shade, Where-the memorandum will be found, thus saving both the search through all the Written leaves or the strain upon the memory to recall its place therein. Besides this a reference at any time to the index will recall to mind any business or engagement requiring present care, and the color at a will show Where the desired directions or information may be found in the body of the book.

The color-matching index is applied to the transfer-lids e in order that in all subsequent inspections of contents or reference thereto it will only be necessary to look through the leaves of one shade or color to find the information sought.

By reason of forming lids c with a flexible hinge a: the main or lon'g part of the lid may be turned back, as shown in Fig. 7, Without casting off the securing-band t, as would otherwise be the result.

Instead of interposing sections m between sections g and h, saidlatter-named parts may be of proper size and be telescopically threaded together; but Where greater adjustment is required the sections m in sufficient number will be employed.

I claim as my inventionl. A book-holder consisting of plates a CL', adapted to be secured to the lids e, and telescopic clamp A, having its opposite sections respectively secured to said plates, substantially as specified.

2. In combination with the leaves p, having the edge notches s, the transfer-lids e e', having corresponding notches, and flexible hinge as, substantially as specified.

3. The combination, in a memorandumbook, of an index duly spaced and provided with representative colors and leaves duly arranged in their respective colors `corresponding to the colors in said index, substantially as specified.

el; The binding-clamp A, formed with a series of cylindrical sections respectively fianged and screw-threaded to engage one Within another and adapted to be telescopicF ally adjusted, substantially as specified.

5. In combination with clamp A, formed and adapted to be telescopically adj usted, the internal flanges fn, arranged to prevent the disconnection of the sections, substantially as specified. y
